How we handle remedial sealant in Boxgrove
Not every leak is a sealant leak. A cracked tray, a failed shower valve or a leaking waste can look just the same. If that is what we find, we will tell you rather than reseal something that won’t fix it. If you are dealing with sealant peeling off a dusty or damp surface and kitchen joints letting water behind the worktop, we can help, on leaking tray & enclosure joints, failed movement joints and botched or over-sealed joints alike.
Around Boxgrove, it’s houses and cottages rather than flats, some with bathrooms tucked into older rooms or extensions. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
There’s a 12-month guarantee on every job, whatever its size.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Use a soft cloth, not a scourer, on silicone
- Do not wait for a small gap to become a leak
- Always have old sealant cut out, not covered
- Find out why the sealant failed first
Where we’ve pointed out another fault, have it put right, because the new sealant cannot hold back a problem underneath.
Leaks through failed sealant grow over time. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
What the job involves on each surface
Over-sealed & botched joints
Thick, smeared sealant looks messy and hides problems. Taking it back shows what’s underneath.
Worktops & kitchens
Old kitchen sealant pulls back from the wall over time. It’s cut out, degreased and resealed colour-matched to the worktop.
What remedial sealant looks like in Boxgrove
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
If you let a flat or house near Chichester station, botched sealant from a previous quick fix is easier to strip out between tenants. For an older house near a landmark such as The Priory Church of St Mary and St Blaize, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you look after a building such as Boxgrove CofE Primary School, we reseal washrooms and kitchens in schools and businesses as well as homes.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
How we quote for remedial sealant
Your quote is based on your job. We take into account:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The amount of work
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
Asking for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- The type of property
- How many joints, rooms or windows are involved
- What’s wrong with the joints now
We don’t publish a price list, because every job is different. Instead, your job gets its own clear quote. To get started, call 0345 464 0079 or email us.
What sealant work cannot fix
To be straight with you, some problems need a different trade:
- Plumbing leaks behind walls or under trays
- A tray or worktop that needs refixing first
- Older mastics that may need an asbestos check before removal
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal

Leave it or put it right?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Around Boxgrove, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.

How it works
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a typical bath or shower, longer where several layers have been applied. For a village or hamlet like Boxgrove, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Getting ready for the visit
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
